THE MAN WHO DIED WASN'T HIM!

The Featured Fact

In X-Men #42 (1968), Professor X died — crushed under rubble alongside the sub-human Grotesk. The X-Men mourned, broke up, and went their separate ways. It was one of the first major deaths in Marvel history, and it stuck for over a year of stories.

It was a lie. X-Men #65 (1969) revealed the dead man was Changeling — Kevin Sidney, a reformed villain with a terminal illness and only months to live, who wanted to atone. Xavier recruited him as a stand-in, lent him a portion of his telepathic powers to sell the disguise, and went into hiding — while only Jean Grey knew the secret.

Why hide? Xavier was preparing a defense against the alien Z'Nox, who were coming to invade Earth. When he resurfaced, he used his vast telepathic powers — plus a psychic gestalt of Earth's compassionate and brave — to drive the Z'Nox off. He had fooled his enemies and his own students at the same time.

Why It's Obscure

Everybody knows Xavier dies a lot. Almost nobody knows his very first death was someone else's — a dying villain doing penance in his chair.

1968

X-Men #42 — Grotesk battle, rubble, a funeral. The X-Men break up and scatter. The death holds for more than a year of issues.

Changeling

Kevin Sidney, ex-Factor Three, terminally ill, months to live. He asks to atone; Xavier gives him the chair, the suit — and a portion of his telepathic powers to make the impersonation hold.

Jean knew

Only Jean Grey knew the man in the chair was an impostor. She grieved in public and kept the secret while the team fell apart.

1969

X-Men #65 — the reveal, and the reason: Xavier spent his hidden months preparing for the Z'Nox invasion, then turned a planet's compassion into a psychic beam that drove them off.
